The Orchard Road area remains under surveillance by the National Environment Agency (NEA), but there have been no new cases of dengue so far.

NEA deems that a dengue cluster is formed when two or more cases occur within 14 days and are located within 150m of each other based on residential and workplace addresses as well as movement history.

The number of dengue cases in Orchard Road reached 93 in November, with more than half of the patients being workers at the Orchard Gateway construction site. It was given a one-week stop-work order in late October when larvae were found there.

There are currently 66 active dengue clusters, with the largest cluster in Kovan. There are 71 reported cases as of Wednesday evening.
